Mountain Time Now

Mountain Time is used across much of the western and mountain states, including cities such as Denver, Salt Lake City, Boise, Albuquerque, and Cheyenne. Phoenix also uses Mountain Standard Time (MST) year-round without daylight saving time.

Mountain Time alternates between Mountain Standard Time (MST) and Mountain Daylight Time (MDT) depending on the time of year.

Does Mountain Time Use Daylight Saving Time?
